This is not directly IP but real food does exist in the diet, so high quality food related sources are good. I think this is a 24 hr sale. I have bolded the ones I either own or will be owning.
Here is a link with some cover images also. http://aweber.com/t/7AFEf

Wow! Thank you! I'll definitely check it out!

Thanks for posting the links! I bought several. Many of the Kindle editions are normally $9 or more. These are a great buy for anyone wanting to try some Paleo recipes. Most are IP friendly.

Aww I'm so bummed that I missed out!!

Lucky:
Most of the links I clicked were still under $2

You're right! I bought a bunch with the really good reviews. Too bad about the Sisson one being full price but the Kresser one is supposed to be good too. Thanks!!

Kresser is also the the author of the link Ro22 posted about Thyroid in the other thread about transitioning.

FYI - Didn't search for them all, but
Credicott
Sisson
Walker
are back to $9.99

Was able to download Kresser's for $1.99
